'This applieaion is: a divisi@ of my pendning patent application SerialNumber 282,520v

filed in the 'nited States Patent Oiii'ce on'` J une 4", 1928,'and' uponwhich Letters Patent No. 1,813,668* Were-issued' on July 7, 1931.

VMore particularly my present Vinvention relates to means for centeringthe die-stock and dies relative to the Work. f

In my' improvedpartible die-st0ck thetv'vo stock-parts are' in hingedrelation t'o each other and centering blocks are slid'ably mounted inthe stock-parts in slideways disposed radially of the Work, and saidblocks are arranged to impinge on the Work and thus.

p stock is closed the plates arecaused' tormove.` 0 in unison so that aunitary movement beim- I partedV to the'bl'ocks.

Other novel features of construction and arrangementof parts Will appearfrom thev following description. y In the accompanyingl drawing, WhereinVI have illustrated a' practical embodiment of* Fig. 5 is a brokensection taken along th line 5--5 in Fig. l.

Referring to the drawing, the partible diestock illustratedtherein is ofthe general con-l Y `struction which is the subject matter of my stockas a center.

portions thereof vvhich are not perse theA subject matter of the presentapplication are" not herein described in fullV butreerence is made tosaid pending patent application for adetailedA description thereof.

The partible die-stock is comprisedy of4 thetWo complementarystock-parts I land la Which are provided at one side` with interlacinghinge leaves 2 pivotally connected to-V gether by the. pintle Each ofthe steckparts 1s provided With af handle 4.; I

The stock-parts are locked intheir closed relation by meansof'the leverland latch 18,

as moreV fully appears in my pending patenti? application.; y

The reaface of the7 stock-parts V1 andlav are provided With pairs ofconverging slide- Ways 22, disposed radially of the axis of the stockwhen closed, in Which sl-idevvays are ,slidably mounted the centering'blocksl23 which are intendedtoengage the Work and properly center thedielstock relative thereto.l

The blocks are provided with pins 24y Which engage eccentricallydisposed slots 25 v of like cam-value in the adjustment leve'rl's26`which are provided with arcuate lips 2'Zon their inner faces whichslidably engage'arcuate undercut shoulders 28 on the stockapartsa 'ArEhe shoulders 2 8 are struck on'an equal radius described fromy theaxis ofthe closed The levers 26 are held in placeby means so as to matetogether When the stock isof-headed bolts 29 .screwed into-'the stock,vparts and'. engagingy slots 3() in'thelever's conclosedand thus tomovetogether about ay common centery sogastof advancev or retract.A

A* By means of the; centering blocks the;stock maybe quickly a-nd accurately centeredrelative to the WorkAThe-independence of the controlofthercentering blocks relative tothethreading dies iswof particular advantage to be tlireaded levers may beheld fixed in placev by tighten-v ing the bolts 29 and thus theadjustment of the centering blocks will not be disturbed; by the openingand closing of the die-stock.

. What-.I desire to claim 'is z- 2 l. In a partible die-stock, thecombination with the stock-parts in hinged relation to each other andarranged to carry the dies,

of work-centering members slidably mounted on said stock-parts formovement toward and away from the axis of the die-stock when closed, alever mounted on eachof said stockparts and provided with surfacesdisposed eccentrically to the axis of the movements of the levers whichengage said'membersto adjust `the position ot the same, and meanswherebyA said levers coactto'move said members in unison whenk thedie-stock is closed 2. In a partible diei-stock, the combination withthe stock-parts in hinged relation to each other and arranged to carrythe dies, of work-centering members slidably mounted on said stock-partsfor movement toward and away from the axisof the die-stock when closed,a lever mounted on each of said stockparts and provided with surfacesdisposed eccentrically to the axis of the movements of theV levers whichengage said members to adjust the Vposition of the same, means wherebysaid levers coact to move said membersin unison when the4 die-stock isclosed, and means for fixing said centering vmembers against movement. o4 v 3. In a partible die-stock, thel combination with the stock-parts inhinged relation to each other, said parts being provided with slidewayswhich are radially disposed relative to the axis of theclosed stock,workcentering members Vmovable in said slideways, aV lever on each ofsaid stock-parts arranged 'or rotary movement, and eccentrical- .wlydisposed slots in said levers engaged by ways, a lever on each of saidstock-parts.

portions of said members whereby when said levers are swung said membersare adjusted arranged for rotary movement, eccentrically disposed slotsin said levers engaged by portions of said members whereby when saidlevers are swung said members are adjusted relative to the axis of thestock, and means for fixing said centering members against movementrelative to th-e stock-parts.

5.v In a partible die-stock, the combination with the stock-parts inhinged relation to each other, said parts being provided with slidewayswhich are radially disposed relative to the axis of the closed stock,workcentering .members movable-in saidgslideways, a lever on each ofsaid stock-parts arranged ;tor rotary movement, eccentrically `disposedslots in said levers engaged by portions of said members wherebyjwhensaid levers are swungsaid members v'are adjusted relative to the axis ofthe stock, and means whereby when the stock is closed the members movein unison whereby a like adjusttions of said members whereby when saidlevers are swung said members are adjusted relative to the axisof thestock, and means whereby when the stock is closed said leversinterengage so as to move 'in unison whereby a like adjustment of allthe centering members is produced.

7. In a partible die-stock, the combination with the stock-parts inhinged relation to each other, said parts being provided with slidewayswhich are radially disposed relative tothe axis of the closed stock,Workcentering members movable in said slide-l ways, a lever on eachofsaid stock-'parts arranged `for rotarymovement, eccentrically disposedslots in said levers engaged by`portions of said members whereby whensaid vleversar'e swung said members are adjusted relative to the axis ofthe stock, means whereby when the stock is closed said leversinterengage so as to move in unison whereby a like adajustment 'ofV allthe centering members is produced, and means for fixing said leversagainst movement relative to the stockparts.
